I know that once I get a primary weapon and a pack, I stay alive for awhile usually, and end up dying at the hands of zombies because they break a leg, or gradually drop my blood down.
But when I die and respawn, I'll often die 2-3 times from a player(being caught with only a Makarov in the big cities trying to find a gun).
Once I'm kitted out though, I usually avoid them unless I'm shooting first.



. Then there is the more obvious ones like spawning RPGs.
